Abstract
Description
Technical Field
[0001] This application belongs to the field of low-carbon building technology, specifically a low-carbon building. Background Technology
[0002] The concept of "low carbon" originates from daily life. Increased carbon dioxide levels lead to global warming, thus giving rise to low-carbon buildings. Low-carbon buildings refer to reducing the use of fossil fuels, improving energy efficiency, and lowering carbon dioxide emissions throughout the entire lifecycle of building materials and equipment manufacturing, construction, and building use. With residents' growing environmental awareness, low-carbon buildings have gradually become a mainstream trend in the international construction industry.
[0003] For general low-carbon buildings, energy-saving technologies such as exterior wall energy-saving technology, door and window energy-saving technology, new energy development and utilization technology, and roof energy-saving technology are adopted. Among them, roof energy-saving technology uses intelligent technology and ecological technology to realize the desire for building energy conservation, such as solar thermal roofs and controllable ventilation roofs.
[0004] However, low-carbon buildings typically do not have rainwater filtration and collection devices on their roofs, so rainwater cannot be filtered, collected, and recycled, which fails to improve the low-carbon and environmentally friendly performance of low-carbon buildings. Utility Model Content
[0005] The purpose of this application is to provide a low-carbon building in order to solve the aforementioned problem of rainwater filtration and collection devices.
[0006] The technical solution adopted in this application is as follows: A low-carbon building includes a building body, a roof fixedly installed on the upper end of the building body, a plurality of grooves being formed on the surface of the roof, inclined water channels being provided on opposite sides of the roof, a water collection trough being welded between the same-direction ends of the inclined water channels, a filter screen being installed at the bottom of the water collection trough, a rainwater filtration device being provided at the lower end of the water collection trough, two adsorption zones being provided at the upper end of the interior of the rainwater filtration device, a water storage zone being formed below the adsorption zones, and a drain pipe being provided on the outer side of the bottom end of the water storage zone.
[0007] By adopting the above technical solution, when it rains, rainwater flows from the groove into the inclined water channel, and then from the inclined water channel into the collection tank. Larger impurities are removed by the filter screen. The filtered rainwater then flows through the filter screen into the adsorption zone for further adsorption treatment to remove remaining fine impurities. The adsorbed rainwater then flows through the adsorption zone into the storage area for storage. The treated rainwater in the storage area is then transported through a drain pipe for recycling. This rainwater filtration and collection device allows rainwater to be recycled, reducing the use of tap water, thus not only reducing water costs but also achieving the goal of low-carbon and environmental protection.
[0008] In a preferred embodiment, a handle fixing plate is provided on the outer side of the adsorption zone, and a handle is welded to the outer side of the handle fixing plate.
[0009] By adopting the above technical solution, when the activated carbon in the adsorption zone needs to be replaced after prolonged use, the adsorption zone can be removed by pulling the handle fixing plate, and the activated carbon in the adsorption zone can be replaced, thereby maintaining the adsorption effect of the activated carbon.
[0010] In a preferred embodiment, waterproof sealing strips are bonded to the upper and lower ends of the handle fixing plate.
[0011] By adopting the above technical solution, the gap between the handle fixing plate and the rainwater filter device is sealed, and rainwater flows out from the gap when the filter is placed.
[0012] In a preferred embodiment, a bolt fixing plate is welded to the outer side above the handle fixing plate, and a bolt is inserted into the inside of the bolt fixing plate.
[0013] By adopting the above technical solution, the plug will limit the handle fixing plate and prevent the handle fixing plate from sliding out of the rainwater filter device.
[0014] In a preferred embodiment, a partition is welded inside the rainwater filtration device between the adsorption zones.
[0015] By adopting the above technical solution, the adsorption area can be limited to prevent the adsorption area on one side from entering the rainwater filtration device too deeply.
[0016] In a preferred embodiment, a drain valve is installed above the drain pipe adjacent to the rainwater filtration device.
[0017] By adopting the above technical solution, the flow rate of treated rainwater flowing from the water storage area into the drainage pipe can be controlled.
[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are as follows: In this application, when it rains, rainwater flows from the groove to the inclined water channel, and then from the inclined water channel into the collection tank. Through the filtration of the filter screen, larger impurities are removed. The filtered rainwater then flows through the filter screen into the adsorption zone for further adsorption treatment to remove the remaining fine impurities. The adsorbed rainwater then flows through the adsorption zone into the storage area for storage. The treated rainwater in the storage area is transported through the drain pipe for recycling. Through the rainwater filtration and collection device, rainwater can be recycled, reducing the use of tap water, which not only reduces the cost of water use but also achieves the goal of low carbon and environmental protection.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] Reference Figure 1-3 A low-carbon building includes a main building 1, with a roof 4 fixedly installed on the upper part of the main building 1. Several grooves 3 are formed on the surface of the roof 4. Inclined water channels 2 are provided on opposite sides of the roof 4. A water collection trough 5 is welded between the ends of the inclined water channels 2. A filter screen 6 is installed at the bottom of the water collection trough 5. A rainwater filtration device 7 is provided at the lower end of the water collection trough 5. Two adsorption zones 12 are provided at the upper part of the interior of the rainwater filtration device 7. A water storage zone 10 is formed below the adsorption zones 12. A drain pipe 9 is provided on the outer side of the bottom end of the water storage zone 10. When it rains, rainwater flows from the grooves 3 to the inclined water channels 2. The rainwater flows from the inclined flow channel 2 into the collection channel 5. After being filtered by the filter screen 6, larger impurities are removed. The filtered rainwater then flows through the filter screen 6 into the adsorption zone 12 for further adsorption treatment to remove the remaining fine impurities. The adsorbed rainwater then flows through the adsorption zone 12 into the storage zone 10 for storage. The treated rainwater in the storage zone 10 is then transported through the drain pipe 9 for recycling. Through the rainwater filtration and collection device, rainwater can be recycled, reducing the use of tap water. This not only reduces the cost of water use but also achieves the goal of low-carbon and environmental protection.
[0025] Reference Figure 1-3A handle fixing plate 8 is provided on the outside of the adsorption zone 12, and a handle 11 is welded to the outside of the handle fixing plate 8. When the activated carbon in the adsorption zone 12 needs to be replaced after a long period of use, the adsorption zone 12 can be taken out by pulling the handle fixing plate 8 through the handle 11, and the activated carbon in the adsorption zone 12 can be replaced, thereby maintaining the adsorption effect of the activated carbon.
[0026] Reference Figure 2-3 Waterproof sealing strips 17 are bonded to the upper and lower ends of the handle fixing plate 8 to seal the gap between the handle fixing plate 8 and the rainwater filter device 7, so that rainwater can flow out from the gap when the filter is placed.
[0027] Reference Figure 2-3 A bolt fixing plate 16 is welded to the outer side above the handle fixing plate 8. A bolt 15 is inserted into the bolt fixing plate 16. The bolt 15 is inserted into the bolt fixing plate 16 due to gravity, so the bolt 15 will limit the handle fixing plate 8 and prevent the handle fixing plate 8 from sliding out of the rainwater filter device 7.
[0028] Reference Figure 2 Inside the rainwater filtration device 7, there is a partition 13 welded between the adsorption zones 12 to limit the adsorption zones 12 and prevent the adsorption zone 12 on one side from entering the interior of the rainwater filtration device 7 too deeply.
[0029] The implementation principle of a low-carbon building embodiment of this application is as follows: When it rains, rainwater flows from the groove 3 to the inclined water channel 2, and then from the inclined water channel 2 into the collection tank 5. After being filtered by the filter screen 6, larger impurities are removed. The filtered rainwater then flows through the filter screen 6 into the adsorption zone 12 for further adsorption treatment to remove the remaining fine impurities. The adsorbed rainwater then flows through the adsorption zone 12 into the water storage zone 10 for storage. The treated rainwater in the water storage zone 10 is transported through the drain pipe 9 for recycling. Through the rainwater filtration and collection device, rainwater can be recycled, reducing the use of tap water. This not only reduces the cost of water use but also achieves the goal of low-carbon and environmental protection.
